Matomo

The Open-Source Analytics Veteran

Matomo started life in 2007 as Piwik and has been the leading open-source analytics platform ever since. It is built around one promise: you own 100% of your data. Self-host it on your own server and Matomo never sees a single visit from your site.

Two Ways to Run It

You can install Matomo on your own infrastructure for free, which is what privacy-conscious teams and many EU organisations do. Or you can use Matomo Cloud, the hosted version with EU data centres and no setup work, billed monthly on traffic volume. Both run the same core product. Self-hosting trades a server bill and some maintenance for total control.

Familiar Reports, No Sampling

If you used Universal Analytics, Matomo will feel like coming home. Visitors, sessions, behaviour flow, goals, the layout is recognisable. Crucially, Matomo does not sample your data. Every report reflects every visit, which is a relief after fighting GA4's sampling. It also bundles heatmaps, session recordings, and A/B testing as add-ons, so it stretches beyond pure traffic analytics.

Privacy by Design

Matomo can run fully cookieless, anonymise IP addresses, respect Do Not Track, and operate without a consent banner in many EU jurisdictions, because it does not share data with third parties. For Spanish and European businesses worried about data protection authorities, this is the headline feature.

The Trade-Offs

Self-hosting is not free in practice. A high-traffic Matomo instance needs a decent server and someone to keep it patched and performing. The interface, while functional, looks dated next to newer tools. Some advanced features are paid plugins on top of the free core. And it has nothing like GA4's native link into an ad platform.
